OHIO C. BARBER CLARK,

OF AKRON, OHIO.

ADJ USTABLE-SOCKET RATCHET-WRENOH.

Application filed August 9, 1919.

To all whom it may concern:

Be it known that I, OHIO C. BARBER CLARK, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useiul Improvements in Adjustable- Socket Ratchetrenches, of which the following is a specification.

This invention relates to tools, particu larly to wrenches, and has for its object the provision of a wrench which is provided with an adjustable socket member whereby nuts of different sizes may be gripped and urned, the socket member automatically adjusting itself to the different. nuts or bolt heads.

An additional object is the provision of a wrench of this character which will be simple and inexpensive in manufacture, which will be very easy to use, which will be efficient and durable in service, and a general improvement in the art.

IVith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which Figure l is a side elevation of a wrench constructed in accordance with my invention,

Fig. 2 is a side elevation of the lower portion taken at right angles to Fig. 1,

Fig. 3 is an end elevation of the socket member,

Fig. 4i is a longitudinal sectional view therethrough,

Fig. 5 is a cross sectional view on the line 'T7 of Fig. 1.

Referring more particularly to the drawings, I have shown my wrench as comprising a shank 10 which is angular, preferably square, in cross section. Carried by the lower end of the shank 10 is a socket member to be hereinafter described, and associated with the top of the shank is a ratchet handle. The socket member at the other end of the shank 10 comprises a body portion 22 which is secured upon the lower end f the shank and which has its lower end formed as a shell 23. This shell portion is provided at diametrically opposite sides with longitudinal slots 24:. Disposed within the shell is a disk 25 provided with recesses 26 having inclined side walls. The recesses 26 diverge with respect toeach other toward the open end of the shell 23.

Specification of Letters latent.

Serial No. 316,430.

The jaw members are designated by the numeral 27 and these jaw members are formed as bar-s disposed within the shell 23 and engaged within the recesses 26. A transverse pin 28 extends through the disk 25 and through the jaws 27, and has its ends extending through the slots 24 in the shell 23. The outer ends of the jaws 27 are formed, as shown at 29, for proper engagement upon a nut. The disk member 25 is slidable within the shell 23 and the sliding movement is locked by engagement of the pin 28 with the ends of the slot 24.

From the foregoing description and study of the drawing it will be apparent that I have thus provided a simple and readily operable adjustable wrench, the socket member of which is adapted for engagement upon nuts or bolts of different sizes, the adj ustment being automatic.

lVhile I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a ratchet wrench, a socket formed as a body having one end formed as an open shell provided at diametrically opposite points with longitudinal slots, a disk member slidab-le within said shell and provided with recesses diverging toward. the open end of said shell, jaw members disposed within said shell and fitting within said recesses, and a transverse pin extendingthrough said disk member, said jaws, and said slots.

2. In a wrench, a socket formed as a tubular body provided at diametrically opposite points with elongated slots, a disk block disposed within said tubular body and adapted to slide therein, said block being provided with spaced recesses diverging toward the open end of the body, a pair of bars constituting jaws disposed with one end within the recesses and their other ends projecting beyond the open end of the body, said bars being provided within said recesses with openings, and a pin extending transversely through said I block, through the openings in said bars, and through said slots.

In testimony whereof I aifix my signature.
